         16 . The automatic system as claimed in  claim 15 , wherein the automatic system is configured so that:
 when hot air is blown into the modular island, the section of the channel of articulated baffles formed between the lower and upper articulated baffles decreases when the inclination thereof increases with respect to a horizontal plane generating a greater blown air velocity favoring the heating mode;   when cold air is blown into the modular island, the section of the channel of articulated baffles formed between the lower and upper articulated baffles increases up to a maximum section of the channel when the two articulated baffles are in the horizontal position generating a low air velocity favoring the cooling mode.

         18 . The automatic system as claimed in  claim 15 , wherein the air suction connection outlet is connected to an air suction duct so as to route the ambient air from the room to an external air-conditioning unit such as a fan coil or an air-handling unit for treating air to be injected. 
     
     
         19 . The automatic system as claimed in  claim 18 , wherein the treated air injected into the internal volume of the modular island via the air blowing connection outlet corresponds to the air heated or cooled and optionally mixed with fresh ventilation air input by the external air-conditioning unit such as a fan coil or an air-handling unit for treating air to be injected. 
     
     
         20 . The automatic system as claimed in  claim 15 , wherein the thermostatic actuation means deploys a stroke of its piston that is proportional to the temperature of the treated air injected into the modular island. 
     
     
         21 . The automatic system as claimed in  claim 15 , wherein the actuation means of the baffles linking the thermostatic actuation means to the channel of articulated baffles is fixed to the upper articulated baffle thus subjecting the channel of articulated baffles to an angle dependent on the temperature of treated air injected into the modular island. 
     
     
         22 . The automatic system as claimed in  claim 15 , wherein the modular island is further provided with at least one light source fixed inside the modular island and allowing illumination of the room, the light generated by the light source being distributed over the diffusion element, such as a taut fabric visible from the room. 
     
     
         23 . The automatic system as claimed in  claim 22 , wherein the modular island is further provided with a light diffusion element such as a taut fabric, and an upper attachment line for the peripheral frame making it possible to attach the light diffusion element below the level of the light source. 
     
     
         24 . The acoustic system as claimed in  claim 22 , wherein the lower articulated baffle serves as a barrier to the light so as not to make the light source visible and/or prevent light from exiting through the blowing slit.
